Notes: 1. In this configuration the device can operate with a minimum input voltage VBAT of 4.0 V (voltage at 33394 VBAT pins).
Notes: 2.VDDL and VKAM are adjustable to support current microprocessor technology (1.25 V to 3.3 V) by means of an external resistor divider.
Notes: 3. When the 33394 CAN transceiver is not used, CANL and CANH pins can be shorted together.
Notes: 4. Dp1 = reverse battery protection diode. Dp2 = load dump protection diode. Dp1, Dp2 can be ommitted in those applications which do not require such protection.
